Hi, I know I've seen this question on this site before, but it didn't explain how to do it. I don't even know where to begin...
Q: Consider the optical interface between crown glass and ethanol.
b) White light travels from crown glass into ethanol. If the angle of incidence in crown
glass is 60.00 degrees, what is the angular spread between the red and violet parts of the visible spectrum in the ethanol? Illustrate your
answer with a light-ray diagram.
index of refraction:
red light in crown glass - n=1.520
violet light in crown glass - n=1.538
red light in ethanol - n=1.363
violet light in ethanol - n=1.376
I think I'm suppose to use Snell's Law...but don't know how. Thanks in advance for your help
